Abstract

La présente invention concerne un procédé de fabrication de fibre optique à cristal photonique ou fibre optique à bande interdite photonique, consistant à fournir une ébauche qui comprend une pluralité de trous dans un diamètre externe, les trous s'étendant d'une première extrémité d'une ébauche à une seconde extrémité de l'ébauche, et à former au moins une fente s'étendant radialement vers l'intérieur à l'intérieur de l'ébauche de manière à ce que la fente croise au moins certains des trous, la fente ne croisant pas au moins un trou. Le procédé comprend également l'étape consistant à établir une première pression dans les trous croisés par la fente en introduisant la première pression dans la fente, et à établir une seconde pression dans l'au moins un trou qui n'est pas croisé par la fente, en introduisant la seconde pression dans une extrémité de l'au moins un trou qui n'est pas croisé par la fente. Le procédé comprend en outre l'étape consistant à étirer l'ébauche dans une fibre tout en contrôlant indépendamment les première et seconde pressions.
